The objective of this work is to propose a chemical management alternative to control Bidens pilosa and Euphorbia heterophylla in genetically modified soybean without affecting grain production and seed germination by using glyphosate applied only once and in mixture, aiming to reduce the number of applications and the amount of herbicides used. The experimental design was randomized blocks with 10 treatments and 4 replications. The soybean used was BRS-Valiosa RR. The treatments consisted of glyphosate and chlorimuron-ethyl applied once and alone (1.5; 2.0 and 80 L or g ha-1 pc), glyphosate in mixture with chlorimuron-ethyl (1.5+10 and 2.0+10 L or g ha-1 pc) and sequentially applied glyphosate (1.5/1.5; 2.0/1.5 and 2.0/1.5/1.5 L ha-1 pc), plus weeded (clean) and non-weeded (dirty) witnesses. The evaluations were: herbicide efficacy in B. pilosa and E. heterophylla, phytotoxicity, density, height and grain yield (kg ha-1) in soybean. The production data obtained were subjected to analysis of variance and F test by the SANEST program (P<0.05). It was concluded that the studied species, B. pilosa and E. heterophylla, were controlled by glyphosate at levels above 90%. There was no visual injury in soybean and no significant decrease in production and germination.
